Active Compensation for a Driving System with Chopper and DC Motor

The paper deals with the behaviour of a load consisting of an uncontrolled rectifier + chopper + DC motor at the supplying from the AC line. The effect of a power active filter over the current absorbed by motor from the AC line (of approximately 100 A rms) is revealed by experimental data. The necessity to protect the DC motor is underlined. A stand with a schema for energy recovering identical to that used for a real driving system from a tram was used. The difference between the active compensation from a tram and its counterpart from the transforming substation AC/AC 20kV/0.4 kV is presented.
